I need to open a new window from a jsp file. In a JSP file, I take in an input from the user and then send it as an argument to a java method which returns me back the url as a string. I then need to open this in a new window. How do I do that? Below is the jsp file(send_product.jsp) for your reference.
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ page import="products.*" %>
<!DOCTYPE html>
<%
productManager pm= new productManagerImpl();
String myUrl= null;
if (request.getParameter("product_id") != null) {
// get the paramter
String product_id = request.getParameter("product_id");
try {
//myUrl has the url. Have to open this in a new window
myUrl = pm.getUrl(product_id);
} catch (Exception ex) {
ex.printStackTrace();
}
}
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert</title>
</head>
<body bgcolor="wheat">
<h4 align="right">Send Product</h4>
<hr color="red"/>
<br/><br/>
<a href="index.jsp">Index</a>
<form action="send_product.jsp" method="post">

Reset to default 3You need to let your JSP print the following line of JavaScript whenever the URL has been received:
<script>window.open('<%= myUrl%>', 'YOUR_WINDOW_NAME');</script>
This way JS will open a new window/tab.
Unrelated to the concrete question, putting Java code inside JSP like that is a poor practice. Be warned!
